Abstract

A case of cystic lymphangioma of the mesentery with severe and persistent abdominal pain in a 22-year-old man is presented. The cyst was filled with chylous fluid. Microscopically, numerous nerve bundles were incorporated within the lymphangiomatous walls, and some protruded into the lumen. The above findings lead to a suggestion that mesenteric lymphangioma may differ from those in the other sites by its abundance of incorporation of nerve bundles into the lymphangiomatous walls, and that increase of tumor size by intracystic accumulation of chylous fluid may subsequently result in increase of intraluminal pressure to compress the nerve bundles with which abdominal pain is much enhanced.
